Nordic Naturals ProOmega Joint Xtra based on the latest human clinical trials, which show that the combination of EPA+DHA from fish oil and glucosamine sulfate work better together than glucosamine sulfate alone.

Most available glucosamine is derived from shellfish, ProOmega Joint Xtra delivers the same highly absorbable and heavily researched form of glucosamine sulfate, but sourced exclusively from non-GMO, organic corn.

UC-II Undenatured Type II Collagen is the primary form of collagen found in cartilage, and promotes the rebuilding of joint cartilage. Many other available forms of Type II collagen are hydrolyzed, which alters the molecular configuration and renders it biologically inactive, the Type II collagen in ProOmega Joint Xtra is undenatured to preserve its native form and thus ensure efficacy.
